Chapter V V-10 JP 3-28 (d) Contracted Support. Contracted support will be the primary means used to accomplish engineer/construction requirements in DSCA. Ample commercial capacity in heavy equipment and materials should be available in the JOA. DOD engineer capabilities coupled with commercial sector and contracted support capabilities provide virtually unlimited engineering depth and breadth. Coordination between USACE and potential construction contracting agencies at federal, state, tribal, and local levels must be conducted to ensure efficient resource utilization and economies of scale when possible. Contracted support can be a significant force multiplier, but it is only one of numerous sources of support to the joint force. Operational contract support (OCS) is the process of planning for and obtaining supplies, services, and construction from commercial sources in support of joint operations. OCS provides tools and processes to manage the variety of services that may be required to support engineer operations as well as base operational support, transportation, food service, sanitation, and security. Contracted support and its associated contractor management challenges must be integrated early in the planning process. For additional information, see JP 4-10, Operational Contract Support. For detailed information on planning OCS, refer to CJCSM 4301.01, Planning Operational Contract Support. (e) Multinational Forces. The availability and possible use of multinational force civil engineering forces should not be considered during mission planning. These forces may be made available to support operations, particularly if a DSCA event occurs in close proximity to national borders. However, DOD component planners should not plan to rely on international assistance as the basis for response and cannot accept military- to-military assistance to meet a DSCA RFA. (f) Environmental. DOD forces employed in DSCA operations are responsible for protecting the environment. Commanders will employ environmentally responsible practices that minimize adverse impacts on human health and the environment. DOD goals are to initiate actions as soon as possible to curtail further environmental damage, resolve environmental impacts, and comply with all applicable laws to the maximum extent possible. 1. During all operations, plans will be developed to reduce or eliminate negative impacts on the environment. DOD will be in support of a primary agency, and environmental responsibilities will remain with the primary agency. However, this does not release DOD from responsibility to plan and conduct operations in a manner responsive to environmental considerations. Timely DSCA response in crisis circumstances may make it necessary to take immediate action without preparing the normal environmental planning documents. Environmental laws often have emergency exceptions. Consultation should be undertaken with staff judge advocates when establishing environmental guidelines when conducting DSCA under emergency conditions. Close coordination with federal, state, tribal, territorial, insular area, and local agencies during DSCA actions is needed to avoid negative environmental consequences. 2. Documenting conditions and actions as soon as possible before, during, and after operations in the JOA will facilitate resolution and closure of environmental issues. An active environmental review of DSCA operations should be
